SPECIFICATION forming part of Letters Patent No. 444,843, dated January20, 1891. Application tiled July 5, 1890. Serial No. 357,807. (Nomodel.)

To all whom, it may concern:

Be it known that we, CHARLES II. BIOHLAND and LEOPOLD KERBER, citizensof the United States, residing at Sigourney, in the county of Keokuk andState of Iowa, have invented eertain new and useful Improvements inGrubbing-Machinesg and we do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

rlhis invention has relation to improvements in stump-pullers; and itconsists in the construction, novel combination, and adaptation ofdevices hereinafter described and claimed, and particularly pointed outin the claims hereto annexed.

In the accompanying drawings, Figure l is a side elevation of ourimproved stump-puller complete, showing parts in vertical section andthe takcsup binding-block in position upon the cable. Fig. 2 is aperspective View of the machine, illustrating the several parts in aposition ready to be applied, and Fig. 3 is a top plan view of thewinding-drum and the pawl for engaging the upper ratchet thereof, theshafts of both reel and pawl being in transverse section. Fig. l is atop plan view of the take-up binding-block with parts broken awayto showthe cable in position in the slots thereof.

In carrying out our invention it is obvious that the most suitablematerial may be employed in the construction of the several elc- 1nentsand that the form of the various parts may be varied to better performtheir functions without departing from the spiritof our invention.

The winding drum or rcel A. has on its upper and lower ends integralflanges B, provided on their periphery with teeth, designed to beengaged and locked by a pawl, oresently to be described, whereby thereel is prevented from backward movement. This reel is prvided on itsupper and lower sides with integral trunnion shafts or journals whichtake into bearings formed in the upper and lower framesections of themachine, and upon the lower flange of the reel we form an integralshouldered disk B', which bears upon the lower section Z of the frameand prevents frictional wea-r of the lower reel-flange. The

upper trunnion or shaft of the reel is reduced or shouldered, asillustrated, and this shouldered portion is provided with ratchet-teeth-O, which are engaged by corresponding teeth upon the lower end of thesleeve D, which is turned by the dreftdcver E, and which serves to turnthe drum and wind the table thereon. The reduced upwardly-extendingportion a of the upper trunnion of the drum is provided with a centralrectangular opening l), of sufficient length to receive a suitable key,and it will be seen that by this construction when the clutch or ratchetfaces of the respective sleeves have been disengaged, as will bepresently described, the cablemay be wound upon the drum through themedium of the key, which may be provided with a suitable crank, ifdesired. Thesleeve D, which is enlarged atits upper portion, asillustrated, is connected by bolts to a metallic plate F, which is of asuitable length and is designed to be attached in turn to thedraft-lever. This plate F is provided at suitable points with ears c,which are perforated, as illustrated, to receive suitable stirrup-boltsd, which straddle the draft-lever and serve to secure the same to theplate.

As an auxiliary means of attaching the leverto the plate, we provideupon the opposite longitudinal sides thereof two oppositely-directedmetallic branches which take over the edges of the draft-lever andprevent lateral displacement thereof. The upright pawlshaft G, which isjournaled in the upper and lower sections, respectively, of the frameadjacent to the periphery of the flanges of the drum, is provided atpoints in its height on the same plane as the flanges with pawls whichare adapted to be thrown in and out of engagement with the teeth of theflanges to lock and release the drum when desired, and are adapted, whendesired, to engage the ratchet-teeth of the flanges and prevent backwardmovement of the reel, and consequently a slacking of the rope. Thepawlshaft extends above the upper section of the frame, where it iskeyed to receive an operating-lever c, the movement of which is limitedby a stop f, as illustrated, and the said stop may be employed, whendesired, to lock the lever in a position of engagement with the teeth ofthe flanges.

IOO

Upon the upper side of the upper section ol.' frame and surrounding thejournal-opening of the upper trunnion we secure or form integraltherewith a collar portion ll, the npper face of which is provided witha ratchet 71 as shown.

I indicates an annulns of an analogous diameter to the collar II, andwhich is provided with a ratchet 7L on its lower side, which rests uponand engages with the clutch of the fixed disk. The ratchet-face annulusI is also provided with a handle 'n for its ready manipulation, and itwill be seen that when said annulus is turned in one direction, so as toraise its teeth upon those of the fixed collar, the sleeve D, theshouldered portion of which bears upon the annulus, will be lifted fromengagement with the ratchet C of the drinnshaft, and when this isaccomplished by simply inserting the key-crank in the opening l) of thedrum-trunnion the cable may be quick] y wound upon the drinn.

The upper section J of the frame, which is of the preferable formillustrated, is provided adjacent to its forward end and upon its underside with two ledges i, which take into two coinciding slots j, cut inthe lower section, and by this construction, in addition tothefastening-pin k, which takes through the sections, it will be seenthat lateral displacement of the sections with respect to each other isobviated.

K indicates a clevis which is secured to the lower section of the frameat one end thereof, and this elevis is adapted for the attachment of ateam when it is desired to move the device. L indicates a clevis at theother end, which is designed to receive an anchor-chain which isattached to a stake or to a tree, and which serves to anchor the machinewhen in operation.

M indicates our improved take-up-cable binding -block, through which therope is passed before and after being looped about the stump, and whichbinds the same and prevents slipping thereof'. This bindingblock, whichperforms the function of a pulley-block, is provided on one side andadjacent to one end with an oblique slot N, as illustrated, which isenlarged or flared at its inner end, and into this slot N leads atunnel-opening O, cut across the block, and adjacent toits opposite endthe block is provided with a transverse slot P, through which the ropepasses before being looped about a stump. Adjacent to the point wherethe tunnel opening in the block intersects the obligue slotihcreoli' wepivot a longue Q, which binds upon the rope and prevents the same fromslipping. h

In operation the cable from the drum is first passed through thetransverse slot P, and after being looped around the stump tobe pulledit is passed through the tunnel-opening O at one side of the tongue Q,and is then looped and seated in the oblique slot on the other side ofthe tongue. New it will be seen that when draft is applied to the cableby the drum and operating mechanism the tongue Q will bind the cableagainst one side of the slot N, and thus thoroughly prevent the samefrom slipping or giving during the operation of pulling the stump.

Having described our invention, what we claim is l. The main framecomposed of the lower section having a hook or elevis at each end, andthe upper removable section J, each provided with vertically-disposedaligned holes, in combination with the double pawl G, journaled in saidholes, the handle on the upper end of said pawl, the drum having flangesat opposite ends provided with teeth, and also having its upper shaftprovided with inclined teeth, the ratchet-ring secured to the upper faceof the upper section J, the collar having a handle and having teethadapted to engage those 0n said section, the draft-beam having a plainblock on its under side,and atoothed clutclrsection depending from saidblock and adapted to engage the teeth upon the shaft of the drum,substantially as specified.

2. In a stump-puller, the combination, with a supporting-frame, of thewinding-drum having the upper and lower toothed flanges B, and the shaftof said drum having a reduced portion at its upper end and aratchet-face at the base of' said reduced portion, a flange surroundingthe shaft of the drum on the upper side of the frame and having inclinedteeth, the ratchet-faced collar, the draft-beam journaled on the shaftof the drum and having a toothed depending port-ion to engage the teethof the drum-shaft, and the pawl G, adapted to engage the toothed flangesB, substantially as specified.

In testimony whereof we afiix our signatures in presence of twowitnesses.
